Is there a bleed valve? I topped up the wated, it was only down a tiny bit but I thought the last person may not have bled it. I'm begining to think il have to remove the head and have a look. I have either replaced or tested most components that make it go. plugs, leads, coils, (havent done distributer) puel pump, pressure at regulator, injectors return line, map sensor, all the fuses, compression, plus a few others that I can't think of. tried the battery to reset the computer but nothing changed.
